admin 14 August 2021

the fear and greed index to gauge the main two emotions affecting the amount of money that traders are willing to pay for different stocks. This index is measured based on four time frames which include daily, weekly, monthly and yearly. Investors use this index to see if the stock market has fair prices. The developers of this index believe that excessive fear will decrease the price of stocks, and a high level of greed has an opposite impact and will increase the price of stocks.

How does the fear and greed index work?

As we already said, investors use this index as a tool to gauge the market. The developers of this index believe that it works based on the logic that extreme fear will lead to trading stocks much below their real value; however, the consequence of extreme greed will be trading the stocks at a much higher value than they are worth. Some pessimistic investors do not accept this index as reasonable because they think it supports a market timing strategy rather than a buying-and-holding strategy.

The fear and greed index uses seven different factors to measure the amount of fear and greed in the market. These seven factors are:

  1. Market volatility: the use of the Chicago Board Options Exchange’s Volatility Index by CNN which is focused on a 50-day moving average.
  2. Stock price momentum: the value of the S&P500 index against the 125-day moving average
  3. Stock price strength: the comparison of the volume of stocks hitting 52-week highs against the volume of stocks hitting 52-week lows in the New York Stock Exchange
  4. Junk bond demand: evaluating the investors’ willingness for high-risk strategies
  5. Put and call options: evaluating the extent to which put options lag behind call options (greed) or surpass them (fear)
  6. Safe-haven demand: comparing the returns of stocks against treasuries
  7. Stock price breadth: comparing and measuring trading volumes in rising stocks vs declining stocks

Each factor is specified on a scale of 0 to 100. The sum values of all factors are divided into seven to calculate the index. When the value of this index is 50, it is considered neutral, but when the higher values indicate greed, while values lower than 50 indicate fear.
